This is a non-profit compendium of car free living and how to build a small electric vehicle with a power system that can climb the steep hills with at least 450lbs total combined weight at a legal wattage. You will not find anything about how to build a fast bike here.
This is the one that I designed and will build myself, leaving the two cranks
for two riding positions. This is very easy to mount and dismount when
fully loaded. Cargo boxes on the front will become very popular when people
stop wasting their money on cars, and find out that they need more cargo room
than just the rear of the long cargo bikes.
You probably will not find a short wheel base cargo bike that has an easy step
through frame to get off the bike, with short legs, without leaning it over to
the side; almost imposable when fully loaded to 350lbs total combined weight;
And you will not find one that has the front rack welded to the frame so that
it will not affect the steering when climbing a steep hill at 3mph (the slowest
balancing speed). WHY!?
Because most people have no idea how to ride it up steep hills. All you have to
do is slide your ass forward a bit to get more weight on the pedals. I learned
this by not being able to ride a prone bike any longer.
Long wheel base bikes are harder to handle in traffic, and there are just plain
heavier than short bikes.
Most people can't afford to own more than one bike; this one can be made from
two old mountain bikes.
The two crank positions are for fitting the person's riding style, or just to
have a much lower gear so that spinning with short crank arms. Most cargo bikes
are made for flat land, this one is for the 10% grades that I climb every day.
